I bought a clubby steer and heifer from a reputable, I trust him, breeder. The steer was vaccinated 2 weeks before I got him. I brought him home and within a couple of days he developed a snotty nose and runny eyes. They both had diaharea, but he got over that. She still has it intermittently. Anyhow, we gave the calf draxxin. Within a day of giving it draxxin the calf develped labored breathing. A week went by and then we gave excede. No change, still runny nose and runny eyes, and snotty breathing sounds from nose. A week later we gave nuflor (different name now) followed with 3 days of bantamine. I don't understand why this 5 mth. old calf is not getting over the breathing issue and snotty nose (sometimes clear, sometimes thick white strands). Can anyone tell me if they have had this problem and what i can give this calf to turn the corner. The heifer has not develped any problems other than runny eyes and somewhat runny nose and seems fine otherwise. By the way the steer calf has never went off feed even with breathing difficulty. They both eat 2 and a half scoops two times a day plus hay. The breathing is very labored. Thanks for any advice.
